SigCom TMH-24G Hazardous Location Tone Signaling Speaker
The SigCom TMH-24G is a self-amplified, explosion-proof tone signaling speaker designed for 24VDC hazardous location mass notification systems. Rated for Class I and Class II Division 1 environments, the TMH-24G is built for use in petrochemical plants, refineries, grain elevators, pharmaceutical facilities, and other areas where ignitable or explosive atmospheres demand certified equipment.
The key differentiator of the TMH-24G from standard hazardous location amplified speakers is its built-in tone generation. Temporal pattern, March Time, and multiple selectable alarm tones are produced internally, so no external tone generator or tone module is needed — reducing the number of components that must be installed and maintained in a hazardous area.
The gray housing suits industrial environments, and 24VDC operation allows seamless integration with DC-powered notification and emergency communication circuits. For a voltage-matched non-hazardous alternative, see the TM-24G. The SigCom TMH-24G combines HazLoc-rated construction with built-in tone intelligence in a single, cost-effective device.
